Title: Our Preoccupation With Protein Intake

Link: https://science.slashdot.org/story/25/09/01/1...

A review of published meta-analyses examining protein supplementation found
no evidence supporting intake beyond 1.6 grams per kilogram of body weight
daily, according to an analysis by cardiologist Eric Topol. The review
examined multiple randomized controlled trials encompassing thousands of
participants. The most widely cited Morton study, which included 1,863
participants across 49 trials, showed no statistically significant benefit at
higher protein levels, with a p-value of 0.079. Recent research from
Washington University identified the essential amino acid leucine as
activating mTOR in macrophages, promoting atherosclerosis progression. The
mechanism was demonstrated in both mouse models and human studies measuring
circulating monocyte changes following acute high-protein challenges
increasing dietary protein from 22% to 50% of energy intake. Current USDA
data indicates 55% of American men and 35% of women already exceed the 0.8
g/kg/day recommendation from the National Academy of Medicine. The protein
supplement industry, exemplified by David bars containing 28 grams of protein
in 150 calories using a modified plant fat called EPG, projects $180 million
in 2025 sales.
